Title: Pseudo error rate measuring circuit
Inventor: FUJINO TADASHI
IPC: H04L1/24
Filed: 1983-03-17
Abstract: PURPOSE:To attain accurate measurement of pseudo error rate by using a regenerated clock phase-shifted so as to identify and regenerate a receiving data signal thereby controlling the sampling point of time of a regenerating device always in the vicinity of the maximum point of the eye opening. CONSTITUTION:An up-down counter CT11 is reset by a reset signal l3 and a pseudo error pulse sampled by a lead clock from a phase shifter 6 at an identifying and regenerating device 3 is inputted to an UP terminal of the CT11 via an EXOR9. On the other hand, the pseudo error pulse sampled by a lag clock from the phase shifter 7 at an identifying and regenerating device 4 is inputted to a DOWN terminal of the CT11 via an EXOR10. The CT11 controls the output phase of the phase shifter 8 based on the count value for a prescribed time and a threshold value. Thus, the output phase of the phase shifter 8 is controlled so that the sampling point of the regenerating device 2 may be at the maximum point of the eye opening at all times.

Filed: 1982-03-24
Abstract: PURPOSE:To prevent a phase locked loop frequency synthesizer from being locked to an erroneous frequency by applying the output from a control circuit to a motor drive circuit after the drive circuit reaches the normal state. CONSTITUTION:The synchronization of a phase locked loop frequency synthesizer 12 is not obtained at the initial starting time of a motor 5, and a synchronization detector 60 conducts the common contact 54 of a changeover switch 48 to individual contacts 50 via a control circuit 61.

At this time the detector 10 produces a synchronization detection signal, and the control circuit 61 switches and conducts the common contact 54 of the switch 48 to individual contacts 49. The motor 5 is driven to obtain a linear speed corresponding to the oscillating frequency of a reference frequency signal generator 42.

Title: Method and device for sliding-boat-type liquid-phase epitaxial growth
Inventor: MUKAI SEIJI
IPC: C30B19/06
Filed: 1979-04-20
Abstract: PURPOSE: To prevent thermal damages of substrates by reducing the heat capacity of a substrate-supporting portion to the very low value, and greatly shortening the time during which the temperature of the substrate is maintained at a high level.  
     CONSTITUTION: There is a slider 3 in which a raw-material solution 2 is contained on a boat 1. The point which is different from the conventional device is that a support 5 of a substrate 4 on which a crystal is grown is independent of the boat 1. A recess 6 for determining the position which accepts the support at a specified position is provided on the boat. The substrate support 5 is placed at a position separated from the main body of the boat 1. At first, the substrate 4 and the support 5 are held at a room temperature. Then, the support 5 is inserted into the recess 6. Since the heat capacity of the support is sufficiently smaller than that of the boat 1, the thermal equilibrium is quickly reached without disturbing the temperature in the furnace. Then, the crystal is grown by the normal process. In this constitution, since the time during which the substrate is kept at a high temperature is greatly shortened, the generation of the defects on the substrate surface can be prevented, and an epitaxial film of high quality can be obtained.

Abstract: PURPOSE:To simplify the circuit structure of the titled device by a method wherein a bidirectional switching element, having memory characteristics, is series-connected to an electromagnet circuit. CONSTITUTION:The division of a lifting electromagnet to be excited is selected in accordance with the objective substance of lifting, a gate signal is outputted to the signal terminal 7 of the pertinent lifting electromagnet 1 from a division selection split signal outputting part 14, a triac 2 is brought into a conductive state and an electromagnet 1 is excited. The triac 2 has memory characteristics, and when a split signal is inputted to the terminal 7 and an excitation current begins to run, the excitation current continuously runs even when the signal sent from the signal outputting part 14 is cut off. When a release operation is performed on the objective substance of lifting, the contactor 11 for release is closed, and a reverse excitation is performed by switching the positive pole and the negative pole of the power source between the terminals 5 and 6 of the lifting electromagnet. At this time, as the triac 2 is a bidirectional switching element, it is in conductive state even when the polarity of the power source is switched. As a result, the number of power feeding wiring, especially the number of moving power source can be abbreviated and simplified substantially.
